An Egyptian court is due to hear on Monday the case against the prominent feminist writer Nawal El-Saadawi, who stands accused of being a heretic against Islam. A Cairo lawyer is demanding that she divorce her husband of 37 years. She has been quoted as saying that the Muslim Hajj pilgrimage to Mecca has pagan roots, and that women should inherit the same as men, instead of half. Dr El-Saadawi, who is a former Director of Public Health for Egypt, was imprisoned in 1980 under the regime of President Sadat for alleged crimes against the state. After her release she received death threats and armed guards had to be stationed outside her home for several years. The BBC's Frank Gardner reports
